ABSTRACT

The present invention is drawn to a composition and method for lifting color and/or imparting shine onto keratinous substrates, the composition containing: (a) at least one phospholipid; (b) at least one nonionic surfactant; (c) at least one compound chosen from an alkyl ether carboxylic acid, an alkyl ether carboxylate, a fatty acid having from about 6 to about 40 carbon atoms, and mixtures thereof; and (d) at least one oxidizing agent. The compositions of the present invention may optionally contain at least one thickening agent, at least one alkaline agent, at least one fatty substance other than a fatty acid, and at least one salt.

FIELD OF THE INVENTION

The present invention relates to novel compositions for lightening thecolor of hair and for imparting shine based on a combination of at leastone phospholipid, at least one nonionic surfactant, at least onecompound chosen from an alkyl ether carboxylic acid, an alkyl ethercarboxylate, a fatty acid having from about 6 to about 40 carbon atoms,and mixtures thereof, and at least one oxidizing agent.

BACKGROUND OF THE INVENTION

It is known that consumers desire to use cosmetic and personal carecompositions that enhance the appearance of keratinous substrates suchas hair and skin by changing the color of the hair or skin and/or byimparting various properties to hair or skin such as shine andconditioning. The process of changing the color of hair can involveeither depositing an artificial color onto the hair which provides adifferent shade or color to the hair or lifting the color of the hair,such as for example, from a dark brown shade to a medium brown or alight brown shade.

The process of lifting the color of keratinous substrates such as hair,also known as lightening, generally requires the use of compositionsthat comprise at least one oxidizing agent. The role of this oxidizingagent is to break down the melanin of hair, which, depending on thenature of the oxidizing agent present, results in a more or lesspronounced lightening of the color of hair fibers. In certain instances,hair lightening compositions may possess an alkalinity such that thesecompositions may have a pH value of above 7 and may require the presenceof an alkaline agent.

In order to improve the performance of compositions for lifting color,the use of new and additional ingredients and novel combinations ofingredients are continuously sought; however, the choice of ingredientscould pose difficulties insofar as they must improve the liftingcapability of the composition without being detrimental to otherproperties of the composition such as its application, rheology orviscosity properties and/or resulting into more disadvantages such asincreased damage or a less healthy look to the hair. It is therefore,important to provide the consumer with a hair lightening or liftingcomposition and method that can lift the color of the hair in anefficient manner, not only to the degree of lift desired, but also withthe added benefit of obtaining better lift compared to current productsand methods without resulting in more damage to the hair. At the sametime, it is also desirable that such a composition and method canprovide other advantageous properties to the hair such as shine,conditioning, and a healthy appearance to the hair. Furthermore, it ispreferable to formulate such compositions that are less costly tomanufacture by requiring less ingredients and/or lower levels ofingredients.

Thus, the objective of the present invention is to obtain novelcompositions for lifting or lightening the color of the hair. Anotherobjective of the invention is to obtain compositions that impartdesirable shine to the hair and other advantages to the hair such asconditioning, a healthy appearance and less damage to the hair. Finally,it is an objective of the present invention to provide a compositionthat effectively lifts color with lowered cost of production.

EXAMPLES

The following example is intended for illustrative purposes only, and isnot meant to unduly limit the scope of the invention in any way.

Example 1 Color Lift Study

Ten (10) g of each of the compositions below were mixed in a 1:1 ratiowith a 20 volume hydrogen peroxide developer. The pH of each finalmixture was about 10. Each final mixture was then applied onto adesignated swatch of natural brown level 3 hair 0.5 cm width, 15 cmlength), commercially available from IHIP, International Hair Importers.

Q.S. Q.S. Q.S. Q.S.

Two control formulas comprising the base formula of a commercialproduct, L'Oréal Preference™ were also applied onto separate hairswatches. Control formula 1 contained 4% ethanolamine as the alkalineagent and control formula 2 contained 10.2% ammonium hydroxide as thealkaline agent.

All swatches were processed for 30 minutes at a 27° C. heating plate,rinsed for 1 minute (80 gph, 32° C.), and dried. Color measurements weretaken before and after treatment as L values which correspond to thedegree of lightness of the color of the hair, using Konica MinoltaSpectrophotometer.

The final ΔL (change in L) value measurements on the swatches treatedwith Formulas A to E were 10.4, 8.62, 7.23, 5.06, and 4.43,respectively. The final ΔL (change in L) value measurements on theswatches treated with control formulas 1 and 2 were 4.21 and 9.63,respectively. A greater ΔL value indicates a greater change in thelightness of the color of the hair which indicates a greater lift incolor. The results show that formulas A to E lightened the color of thehair significantly better than or comparably to the control formula 1,while formulas A, B and C which contained sodium sulfate lightened thecolor of the hair significantly better than formulas D and E which didnot contain sodium sulfate. Moreover, formulas A to C required a loweramount of the alkaline agent, monoethanolamine, compared to that used informula E and control formula 1 in order to achieve significantlygreater lightening effects; this is more advantageous since lower levelsof the alkaline agent are more desirable. As for control formula 2, thisformula contained a higher level of alkaline agent, that is, 10.2% ofammonium hydroxide, which is less desirable.

It will be apparent to those skilled in the art that numerousmodifications and variations can be made without departing from thespirit or scope of the invention.
